Neodymium is the fourth member of the lanthanide series. In the periodic table, it appears between the lanthanides praseodymium to its left and the radioactive element promethium to its right, and above the actinide uranium. Its 60 electrons are arranged in the configuration [Xe]4f 4 6s 2, of which the six 4f and 6s electrons are valence.
Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...
Scientists. v. t. e. Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping.
Rubidium. body-centered cubic (bcc) (cI2) Rubidium is a chemical element; it has symbol Rb and atomic number 37. It is a very soft, whitish-grey solid in the alkali metal group, similar to potassium and caesium. [8] Rubidium is the first alkali metal in the group to have a density higher than water.
Cerium is a chemical element; it has symbol Ce and atomic number 58. It is a soft, ductile, and silvery-white metal that tarnishes when exposed to air. Cerium is the second element in the lanthanide series, and while it often shows the oxidation state of +3 characteristic of the series, it also has a stable +4 state that does not oxidize water.
Selenium. Selenium is a chemical element; it has the symbol Se and atomic number 34. It has various physical appearances, including a brick-red powder, a vitreous black solid, and a grey metallic-looking form. It seldom occurs in this elemental state or as pure ore compounds in Earth's crust.
Bastnäsite crystal from the Manitou District, El Paso County, Colorado, USA (size: 4.3×3.8×3.3 cm) Bastnäsite has cerium, lanthanum and yttrium in its generalized formula but officially the mineral is divided into three minerals based on the predominant rare-earth element. [6] There is bastnäsite- (Ce) with a more accurate formula of (Ce ...
Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet.
